CARTRIDGE FUSE,

Application filed July 7, 1920. Serial No. 394,429.

T 0 all 2071 am it may concern:

Be it known that I, IJAJZUEL R. Ronnrenns, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Cartridge Fuse, of which the following is a specification, the same being a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cartridge or other enclosed fuses and particularly to that class or type of the same in which the burntout fuse element may be replaced by a new one and which are commonly designated as renewable fuses; and it has for its object the provision of means whereby the fusible element may be readily adjusted and pre vented from getting out of alignment, and whereby torsion of the same is eliminated.

Another object of the invention is to hold a plurality of fuse element retaining memhers, as disks or plates, superposed on the end of the fuse casing and preferably enclosing the bent over end of the fuse element in order to prevent the latter from falling when the adjacent metallic cap of the fuse is removed.

With the above and other objects in view, all of which will be clearly set forth in the following description, I have designed a fuse simple in construction, inexpensive to manufacture and efficient in practical use.

In the drawings, which accompany and form a part of this specification and illus trate one embodiment of the invention,

Figure 1 represents an elevation partly in section of a fuse constructed according to my invention;

Figure 2 is a plan view of the same with the cover removed;

Figure 3 is a plan view of another fuse in which the invention is embodied; and

Figure 4 is a detail sectional view of the latter.

Referring specifically to the drawings. the cylindrical fuse casing l, which may be of any approved or desired construction, ordinarily has at the end thereof a ferrule 1' and is also ordinarily provided with a metallic cap or closure 2 which may be screwed upon or otherwise held to the said end portion of the said casing, Intermediate the said closure and the end portion of the casing is attached in a movable relation to the said, end portion or ferrule a dual supplemental closure comprising two disk members 3 and 4 which may be held to or at the upper face of the ferrule, as by being linked thereto, by means allowing a relative movement of the said members, as by a hinge, joint or pin 5, so as to allow at least one of the said members to be swung away from its normal posi tion, as in the present instance by the movement of the member 3 in an outward direction away from the upper face of the casing.

I prefer, however, to provide means to hold both of the said members in a movable relation and to make the various parts so that the members 3 and 4, when in normal position, form a complete closure for the fuse casing.

When the member 3 is swung outwardly and preferably horizontally, the end of the burnt out fuse 6 which overlaps the member 4 may be removed. When the parts are in this position a. new fuse may be inserted in the casing and the end thereof bent over the member 4 whereupon by moving the upper member 3 back to the casing the fuse end will be snugly caught between the members 3 and 4; and held so securely that it cannot become twisted or loosened or otherwise disarranged by the screwing on of the cap 2.

It is obvious that if the members 3 and 4 were not held to the casing in a movable relati on, but were to be structurally lndependent thereof, the said members would be liable to fall to the floor when the end of the fuse element was disengaged from the casing. which operation would entail either a loss of the said members, or a waste of time in looking for the same.

I sometimes construct one of the members of the supplemental closure in the form of a complete disk, as at 3 in Figures 3 and 4. the operation of which is similar to that of the disk 3 already described.

I wish it to be understood that I do not desire to be limited to the particular use or the exact details of construction shown and described, for obvious modifications will oc our to persons skilled in the art.

What I claim as my invention is 1. In a device of the class described. a casing, a closure therefor, a dual'memher attached in a horizontally movable relation at the end portion of the casing and comprising a supplemental closure, and a fuse element the end of which is held between the members of the supplemental closure.

2. In a device of the class described, a casing, a closure therefor a fusible element a and arranged to form an entire closure for the end portion of the casing.

4. In a device of the class described, a casing a closure therefor, a dual supplemental closure hinged at the end portion of the casing and constructed and arranged to allow the free attachment or removal of a fuse, and a fuse element the end of which is held between the members of the supplemental closure.

Signed at Brooklyn, in the county of Kings and State of New York this 18th day of June, A., D. 1920.
